CHARLES J'. TAG-LIABUE, OF BROOKLYN, NEW YORK, ASSIGNOR TO C. J'. TAGLIABUE MANUFACTURING COMPANY, A CORPORATION OF NEW YORK.

CLOSED OIL-TESTER.

Application filed August 14, 1915.

To all whom it may concern:

Be it known that 1, CHARLES J. TAGLIABUE, a citizen of the United States, resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Closed Oil-Testers, of which the following is a specification.

My invention relates primarily to an improved closed oil tester wherein a burner tip is adapted to be lowered into an opening in the cover above the oil cup simultaneously with the opening of the lid. Various devices have been constructed for opening the lid of the closed oil tester and lowering a flame into the opening to ascertain the flash point of an oil being tested, but most of these devices are more or less crude and inaccurate in operation, because of the lack of coordination between the sliding lid and the burner or tip of flame which is to give the flash.

The object of my improvement is to coordinate these parts in such a way that there is a positive connection between the burner and the sliding lid whereby the lid will be opened simultaneously with the lowering of the burner ti into the opening of the cover. I also provide the burner tube with a retracting spring adapted to restore the burner to normal position and close the lid. The arrangement is such that the manipulation of the device is at all times under control of the operator, a knurled finger wheel being provided for simultaneously lowering the burner and opening the slide of the cover. One form of my improved device is shown in the accompanying drawings in which Figure 1 represents a vertical cross section through the apparatus along the line 11 of Fig. 2, the base thereof being broken away; Fig. 2 is a top plan view and Fig. 3 1s a sectional view of the lid and upper part of the instrument along the line 33 of Fig. 2. Referring to the drawings 1 represents a water bath conveniently supported upon a base member 2 the bath being adapted to be heated in the usual or any preferred manner. The bath is provided with an annular cover 3 having a central upwardly extending annular flange 4 adapted to support an oil cup 5 substantially as shown in Fig. 1 of the drawings. The annular cover 3 is provided with a projecting tubular opening 6 in which a plug 7 carrying a thermometer 8 is adapted to be inserted so that the temperature of the water in the bath may be ascertained.

flanged cover disk 9 is adapted to fit snugly over the central annular flange & of annular cover 3 and close or cover the oil cup 5. The cover 9 is provided with a tubular opening 10 in which a plug 11 carrying a thermometei- 12 is adapted to be inserted for ascertaining the temperature of the oil. The cover 9 is preferably provided with a central opening at 13 and two smaller openings in line therewith at 14 and 15 substantially as indicated in dotted lines in Fig. 2 and in the section shown in Fig. 3 of the drawings. Parallel with these openings on each side thereof the cover is provided with slide ways 16 and 17 each provided with an inwardly extending lip adapted to overlap the sliding cover plate 18 substantially as indicated in Fig. 1. The cover slide or lid 18 is provided with an opening at 19 adapted to be brought into registry with the central opening 13 in the cover 9 to open the same; but normally the slide is adapted to close the opening 13 as shown in Fig. 2 of the drawing. The slide or lid 18 is also provided with another opening at 20 adapted to be. brought into registry with the opening 15 when the opening 19 is in registry with the opening 13 of the cover. The opening 14 in the cover is so located as to be exposed or opened when the lid 18 is moved to open position. The openings 14 and 15 in the cover are vent openings and the central opening 13 is adapted for the insertion of the light to ignite. the vapor for the flash test. At one side of the center of the cover 9 and preferably mounted upon the bars 16 and 17 respectively are upright posts or bearings 21 and 22 adapted to support a gas tube 23 mounted above and transversely of the sliding lid 18. The tube 23 is suitably mounted in the bearing posts 21 and 22 for rotation therein and is provided with a burner tip 24 located substantially central of the lid, the tip end 25 being adapted when lowered to enter the opening 13 through the opening 19 in the lid when the two openings are in registry. The gas tube 23 is preferably provided with a stop cock 26 for adjusting the size of the flame at the tip 25 and a suitable nipple 27 is connected by means of a rubber tube 28 with a gas supply in the usual or any preferred manner.

The opposite end of the gas tube 23 is preferably closed by means of a longitudinal extending spindle 29, the outer end of which is provided with a knurled finger Wheel 30 by means of which the tube 23 may be turned to lower the burner tip into the openings 13 and 19 as hereinbefore indicated. A spring 31 is preferably coiled about the spindle 29 and adapted to turn the spindle in a direction to lift the burner tip and hold it and the lid 18 in the normal position indicated in Figs. 1 and 2 of the drawings.

It is desirable that when a test is to be made the burner 25 shall be lowered into the opening simultaneously with uncovering the same. This I accomplish by providing the rotatable gas tube '23 with a downwardly projecting arm 32 adapted to engage with a slotted or forked member 33 secured to and projecting from the upper face of the sliding lid 18 substantially as indicated in the drawings. From this arrangement it will be seen that by turning the gas burner down by means of the knurled finger wheel 30 the sliding lid 18 will be moved simultancmlsly therewith until the opening 11) is brought into registry with the central opening 13 of the cover at which time the burner tip 25 will be substantially in the position shown in Fig. 3 of the drawing, with the flame in position to ignite the confined vapors. The temperature of the oil may be ascertained at any time by means of the thermometer 12 and should be observed each time the finger wheel 30 is turned to open the cover and make a test. \Vhen the test has been made the operator merely releases the finger wheel and spring 31 will immediately restore the parts to normal position by turning the gas tube thereby lifting the burner and closing the cover opening 13. The size of the tip of flame at may be regulated by means of the stop cock 26 the size being gaged by a bead 34 located on the cover 9 in the usual or any preferred manner. The sliding lid 18 is preferably provided at 35 with a depending stop pin adapted to cooperate with the walls of the opening I?) in the cover and limit the movement of the lid and also of the 'burner.

Various modifications in the specific detail of construction may be made without departing from the spirit and scope of my invention.
